Large Valve Expertise

Valves come in a variety of sizes, from fit in your hand types to giant 40-foot-tall, 72,000-pound monsters. It takes unique infrastructure, equipment and expertise to repair, modify or service these giants of the flow control industry. At United Valve we rely on a purpose-built 42,000 sq. ft. repair building, designed to handle the largest valves and flow control devices. The 56-foot-tall repair building contains 40-ton, 20-ton and 10-ton overhead cranes which allow us to easily handle valves of nearly any size and weight. Large-bore valve machine tools are also located in this building, including a 20-foot table, Farrell vertical boring mill that can handle components up to 20 feet tall. An additional 102” vertical mill is also located in this building, along with internal and external grinding machines for large-diameter rising-rotating plug valves. Welding positioners for the heaviest valves, along with submerged-arc and cold-wire TIG welding units provide ample welding and joining capability in the repair shop. Additional machine tools, including CNC equipment, are located in the adjacent 60,000 sq. ft. production building. Our large valve testing capabilities include a very large Porgetti horizontal testing machine encased in a large timber-lined steel bunker. This unit can test the largest API 6D ball or gate valves. An 850-ton vertical test machine for testing large, high-pressure butt-weld end valves is also located in the building.
